Electrocardiographic current derivation electrode

Abstract

An electrocardiographic current derivation electrode is disclosed, which consists of a substantially rectangular lamination consisting of a resin film, a deposited silver layer formed on one surface of the resin film, a conductive adhesive layer coated on the deposited silver layer and a foamed sheet applied to the outer surface of the resin film. The electrocardiographic current derivation electrode is formed in a substantially central portion thereof with a substantially parallelogrammic terminal. One short side of the terminal is foldably united to the rest of the electrocardiographic current derivation electrode, the other three sides of the terminal are cut sides, and the long cut sides of the parallelogram are not parallel to the long sides of the substantially rectangular electrocardiographic current derivation electrode.

What is claimed is: 
     
       1. An electrocardiographic current derivation electrode consisting of a substantially rectangular lamination having a pair of opposing short sides and a pair of opposing long sides, said lamination consisting of a resin film, a deposited silver layer formed on one surface of said resin film, a conductive adhesive layer coated on said deposited silver layer and a foamed sheet applied to the other surface of said resin film, said electrocardiographic current derivation electrode being formed in a substantially central portion thereof with a substantially parallelogrammic terminal, said terminal having first and second opposing short sides and a pair of opposing long sides, said first short side of said terminal being foldably united to the rest of said electrocardiographic current derivation electrode, the other three sides of said terminal being cut sides, the long cut sides of said parallelogrammic terminal being inclined to the long sides of said substantially rectangular lamination and having stem ends at their junction with said first short end. 
     
     
       2. The electrocardiographic current derivation electrode according to claim 1, wherein the long sides of said substantially parallelogrammic terminal have outwardly curved stem ends. 
     
     
       3. The electrocardiographic current derivation electrode according to claim 1, wherein the long sides of said substantially parallelogrammic terminal have stem ends in the form of circular holes.
